The Chelsea 871LDFJW-B5TS or 871LDFJWB5TS is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series supports continuous torque up to 670 lb-ft (908 N-m) and is rated for continuous-duty operation without derating. Nine speed ratios and thirteen output options cover a wide range of driven-equipment requirements, including fire and rescue, refuse, truck cranes, and pumper cleaner applications. This unit carries forward Chelsea's ductile iron bearing cap, 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap to counter vibrational loading from modern engine designs. The wet spline pump flange protects both PTO and pump shaft over the long run. Call us to confirm proper fit for your specific Allison transmission and application.
The 871 Series replaces the Chelsea 870 Series PTO, carrying upgraded materials and sealing throughout. Common markets include fire and rescue, refuse, truck cranes, and pumper cleaner equipment. Shaft power for the 871 Series is rated at 64 HP at 500 RPM and 128 HP at 1,000 RPM (48 kW at 500 RPM, 95 kW at 1,000 RPM).
